摘要 目的:探讨白质纤维束成像(Diffusion tensor tractography,DTT)技术在脑星形胶质细胞瘤研究中的价值。材料与方法:对33例经病理证实的脑星形胶质细胞瘤患者进行常规MR成像、弥散张量成像(DTI)和DTT,分析肿瘤瘤周白质纤维束的改变形式与肿瘤分级的关系。结果:无论是高级别还是低级别肿瘤,瘤周白质纤维束都可以发生移位(77.78%～100%),而白质纤维束的破坏和中断主要与星形胶质细胞瘤的恶性程度有关,随着肿瘤级别的升高,白质纤维束的破坏和中断的发生率也逐渐升高(7.69%～72.73%)。结论:DTT技术在显示脑星形胶质细胞瘤分级方面有重要的价值。 Objective： To evaluate the value of diffusion tensor tractography （DTT） in brain astrocytomas. Materials and Methods： Thirty-three patients with histologically confirmed astrocytomas underwent routine MRI, DTI, DTT, analyzing the changes of white matter fibres around the tumors and specific conditions in different grade of astrocytomas. Results： There is displacement of white matter fibres around tumors whether low-grade tumors or high-grade tumors （77.78%-100%）. Disruption and interruption of white matter fibres around tumors are related to malignancy of astrocytomas. The higher the grade of tu- mor, the higher incidence rate of white matter disruption and interruption are （7.69%-72.73%）. Conclusion： DTT plays an im- portant role in revealing the grade of brain astrocytomas.
